To all whom it may concern.'

Be it known that I, JOSEPH E. ANGEL, a citizen of the United States, residing in Madison, in the county of Rockingham and State of North Carolina, have invented4 certain new and useful Improvements in Printing- Presses, of which the following is a specification.

My invention relates particularly to the paper feed mechanism of printing presses and the objects of my invention are to provide novel means whereby sheets of paper of any thickness may be automatically taken, one by one, from a magazine or reservoir, printed and then discharged to a suitable receptacle.

In' carrying out my invention in the pre ferred way I store the sheets of paper to be printed in a magazine or reservoir above a table or support which is automatically elevated step ,by step, -as the work progresses, to hold the top sheet of paper in proper position to be engaged by a pneumatic withdrawing device or sucker which is reciprocated above the magazine and which elevates a single sheet above the top thereof and holds it until the magazine has moved from under it and the type bed is moved beneath it, the withdrawing device or sucker being then made to descend and press the paper against the type and the printing in this way is perfected. 'l`he sucker thus not only serves to raisethe paper, but also to hold it, and, acts as a platen to press it against the type. As soon as the sheet is printed the Sucker rises and releases the printed sheet which is' rcceiycd by a deliver-er that is operated to convey the printed sheet to a suitable receptacle. The magazine and type bed are then shifted so as to bring the magazine under the sucker so that when it next descends, it will engage a 'sheet and thereafter the operations are repeated in the manner above described. I may shift the magazine and type bed back and forth in a straight horizontal plane, or I may cause them to swing about a horizontal axis, or I may merely shift the type bed into and out of position under the sucker. I also may so mount the sucker as to swing hack and forth while the magazine and type bed are held in a fixed position.

The magazine is provided with devices whereby the raising of a single sheet only is y insured and should the sucker fail to raise a sheet at the proper time, mechanism is provided whereby the type bed is lowered so that the sucker will not then descend upon it. Mechanism is also provided whereby should the paper pile be fed too rapidly upward, thc feed is automatically stopped or retarded, and when the pile of paper is nearly exhausted, the machine is automatically stopped by slipping the driving belt. I have also provided mechanism whereby, if the sucker should fail repeatedly to lift a sheet from the magazine, the machine will be stopped automatically by shifting the driving belt.

By the above described mechanism, the machine will normally raise sheets of paper one by one from a magazine, print them and deliver them to a. suitable receiver, but should the machine fail for any reason to properly feed, the feed operating mechanism will beA automatically arrested, or if necessary, the machine will be stopped.

In addition to the mechanism above mentioned, my machine involves other features of construction, among which may be mentioned the means for automatically operating the inking roller, the means for holding a folded sheet of paper in position on the sucker, and theidevices for so operating this holding means that it will properly operate to move into holding position immediately after the' sucker has lifted a sheet from the reservoir and then be automatically withddrawn to allow the folded printed sheet to be delivered.

In the accompanying drawings I have shown the best way now known to me of, carrying out my invention. The preferred mechanism is illustrated in the first 18 figures of the drawings, while some of the contemplated modifications are illustrated in the other figures, but I wish it understood that other modifications of thc mechanism may be made without departing from my invention. I. have merely illustrated a few of the many ways in which it may be embodied.

Figure 1 shows a front elevation of the i'nachinc. Fig. 2 shows an end elevation of the righthand side thereof. Fig. 2 is a detail view of the inlet valve-of the pumpn Fig. 3 shows a vertical central section on the line 3-3 of Fig. 2. Fig. 4 is a detail view showing particularly the mechanism for delivering the printed sheet to a rece facie and the relation thereof with the sucker, the magazine and the type bed7 thel mechanism being shown in position for the deliverer to receive a printed sheet. Fig. 5 is a view similar to Fig. 4 showing the deliverer in the act of depositing a printed sheet in a receptacle.

Fig. 6 is a' detail view of a stop cooperating with the horizontally moving magazine and type bed.- Fig. 7 is a view on an enlarged scale and in perspective of the mechanism for elevating the pile of paper and the means for arresting this feed mechanism and l'or stopping the operation of the machine. Figs. 8 and 9 are detail views of the nut forming part of the feed mechanism shown in Fig. T 8 shows the relation of the nu t with the feed screw. Fig. 10 is a detail view showing particularly the means for holding a folded sheet on the sucker. Fig. 11 is another view of the saine mechanism. Fig. 12 shows the construction o'l' certain parts of the magazine and illustrates particularly the devices for retarding the withdrawal of the sheets so that only one sheet at a time will be withdrawn. Fig. 13 is a detail view of one of the suction openings of the sucker. Fig. 14 is a lan view of the bottom face of the sucker.

igs. l5 and 16 are detail views of the retarding devices of the magazine. Fig. 17 is a detail view in perspective illustrating particularly the mechanism vfor arresting the printing operation and for stoIpping the machine by shifting the driving be t. Fig. 18 is a perspective view ofthe delivering device. The remaining fig res of the drawings show modiications. Fig. 1 shows an organization in which the sucker is arranged to reciprocate vertically and also to swing back and forth over the ma azine and type bed, which latter areheld in igixed positions. Fig. 19 shows a vsection on the line 19-19 of Fig. 20, and,

Fig. 2O shows an end elevation of the mechanisin shovm in Fig. 19. Fig. 21 is an end shown, has a `hollow body to which is connected a flexible pipe i connectedalso with a puni p K. lts bottom is ilat and is provided with a n uinber of holes t" which are litted, as shown in Fig.. 13, with rubber rings 2, or, as shown in Fig. 10, each rubber ring is carried by a metallic ring i, held in place by a flanged threaded ring i4 engaging the inwardly projecting hollow boss i in which the hole i is located. spring i" presses the rings 112, i3 outwardly. ln either case the rings yield when the sucker is pressed upon the paper or when the sucker descends with the paper upon the type and a tight engagement is effected so that the pneumatic. action will be complete, and when printing, the paper is made to fit smoothly on the type.

'The pump K is operated from the countershaft F by means of a mutilated pinion F thereon n hich meshes with a vertical rack bar F2 which is prolonged into a shank F3 Jliat terminates at the point -7, indicated in ig. 3.- in suitable guides F? and is lifted by the mutilated gear, but is made to descend by a spring F5 attached to an arm FG projecting from the shank of the rack bar and connected at its lower end to the frame A. The purnp cylinder has an inlet at its lower end controlled by a spring pressed valve k, the tension of which may be regulated in any suitable'way, and the tube i is connected to the lower end of the cylinder as shown. The piston rod K is connected at K2 with a coiled spring K3, the upper end of which is connected at 7c to the shank ofthe rack bar F2.

Normally the operation is as follows z-As the shaft F rotates, the piston rod is raised elevation, and Fig. 22 is a side view of an |'through the medium ofthe mutilated gear organization in which the type bed is ar- F and the rack bar F2, and the s ring K3 ranged over the top of the magazine and is whichgis connected to the piston ro but the mounted -to swing' back and forth into position over the magazine and also to one side thereof. Figioa illustrates an organization in which thenjtype bed and magazine are mounted to swing about a horizontal axis'.

The main frame A of the machine may be of any construction suitable to support the moving arts. The driving shaft B carries a fly-Whoo C'and fast and loose pulleys D, E, and the vdriving shaft is eared witha counter-shaft F by spur whee s G, H. T he'driving shaft is formed with a cranked portion Z) to which is jointed a piston' rod l connected at its lower end with a cross head I mounted to reci rocate' vertically in suitable guides I2 of t e frame. To this cross head is lattached a pneumatic withdrawing device or.

sucker J which is designed to elevate sheets of paper one by one from the magazine,4 press them upon the type and drop the rinte`d sheets to r deliverer in the mannerl creinafter descriwd. The withdrawing device, or as it will be hereinafter called, the sucker, as

-of paper is mounted on a support M upon nhich also mounted a frame N carrying the typebed Q. rEhe support M is carried o n rails M attached at their inner ends to a horizontal shaft M2 carry/*ing a toothed segment M21 and formed lwith a crank M4 with ln this construction a The rack b ar reciprocates vertically 'which is connected a rod M5 vextending upwardly to a strap M surrounding an ecce-ntric M7 on the counlter-shait'F.- The outer p ends of th rails lvl-are supported by rollers m inountedon a horizontal shaft wif-carriedv agms mg'pivptally connected, as shown at ma'inFi 2, with the frame A. Mechanism 1 g 1 1 is provi ed, as w 1li be hereinafter described, whereby .the rollers may be raised and lowered to correspondingly raise and lower the rails li, andthus raise and lower the paper magazine' and the type bed. The sup'L lrt M is provided with a rack bai' m5 engaging the segment M3 and the arrangement is such that the support M is` reciprocated horizontally iii such way as to bring the magazine and the type bed alternately into a position below and out of the path of the sucker. 'lhe magazine L is rigidly connected with the support M. It preferably comprises lower .side

l plates l, slotted horizontally at l and con Both the rigid bottom and the false, or yielding, bottom are adapted to move vertically in and be guided by the angle irons l. The false bottom is recessed or grooved at l5 and through this portion projects a bolt l for a` purpose hereinafter explained.

In order to insure that only one sheet of paper, card, or envelop shall be'iiithdravn froin'the magazine at a time, l have provided retarding devices which act upon the edges of the papel', card or envelop, and

`-uhile they permit a single sheet carried by the sucker to be uithdrawn, they prevent the withdrawal ot' all others. By reference to Figs. l2, 15 and 16, it will be seen that the corner pieces, or angle irons .Z3 each carries` a vertical series of inwardly projecting pins Z7 and each corner piece carries a hook Z8, the

lower end of the shank ot' which is secured at l to the outside of the corner piece, while the upper hooked end thereof, nhich is preferab y in the form shown in Fig. 16, extends through a 'slot l1 in the upper edge of the corner piece, and projects into the path of the paper as it is raised. Furthermore, each corner piece is provided v. ith a strip of rub berl or other soft anti-slipping material l which is arranged in a vertical slot in the corner Zpiece and is secured to a thin, tlat spring 2 secured at its lower end Z1 to the angle iron. The strip l acts u`pon the edges of the sheets and retards their upward movement., but the pressure exerted thereby, or the retardiiig action, is not such as to .prevent or retard materially the \\'ithdravi al ol' the topmost sheet engaged by the sucker. ln like manner the hook Z8 by'reason ol` its thinspring shank will yield to permit the the strips l and the pins Z7, the hooks will insure their retention.

In connection with the devices for pre-4 venting the nithdrav. al of duplicate sheets l l l from the magazine, l may also employ a blowing device N, This consists of a pump having a discharge port nl" at its upper end just above the top ofthe pile of )aper sheets. 'l`he piston rod extends upwardiy and in the path of an arm N* projecting from the cross head l. As the cross head ll descends the piston'is depressed drawing air inat the port n", but as the cross head l. rises, air is blown out through the port um so that should two or mori` sheets by any possibility be raised by the sucker they n ill be blonn apart and separated by the jet of air issuing from the nozzle n". y

The type bed O is spring supported on the frame N and this frame with theinagazine frame, on which it is supported, are firmly connected with the support M, and as the shaft M2 is oscillated, the magazine and type bed are moved back and forth alternately into position below the sucker. In order to insure that the magazine and type bed shall stop in proper position to be acted upon by the sucker, I have provided flanges M of the support M with recesses 7i in its side plates which are engaged by rollers n carried by spring pressed Shanks n? in the main frame A. These rollers engage the recesses n at the ends of the movements in both directions.

The pilel of paper X, (Fig. 12) rests on the false bottom L3 which is supported by the bottom plate L2 which latter is rigidly secured at i to an arm P to `hir-.h is pivotally connected'at p a nut P of the form sho\\ 11 in Figs. S and E). This nut engages a vertical screw P2 and as the screw is rotated, the nut is raised and the pile of paper correspondingly 'raised As illustrated in Figs. 8 and 9, the nut is formed with a hole p2 v.hich is larger in diameter than the screw P2. The hole p2 has a threaded portion p on one side of its lower portion, and a threaded part p on the opposite side of its upper portion, so that. when the nut is tilted in the uiaiuier shown in Fig. 8, the screw uill engage the threads p and p, but uhen the nut is turned so that its axis coincides with the axis ol' the screv., the threads p3 and p* will be disengaged l'roin the screw and the nut v. ill l'reely mme up and down without being iuipeded by the screw. 'l`hc nut is l'ormed uith an arm P" carrying a latch handle P5 to \\hich is coinected a bent rod l adapted to engage a latch lug' p" on the top ol' theI nut. Villen theI rod F is thus engaged uitb thc latch lug p, the nut is tilted and engaged by the screw l, but by properly operating the latch handle P5, the latch rod P may be tdisengagcd'from the lug p, and then bv withdrawal of the topmost sheet, but should -any follouing sheets .tail to be retained by depressing the handle or arm l", the nut may be disengaged l'roin the scrivev and lov` ered, thus louering the pileI ol' paper or supporting plates lf, lr". At its upper end the screw P2 is mounted to turn in a bearing P7 attached to the top ol' the frame N :und at i io its lower end the screw is mounted to turn in a bearing P5 attached to the bottom of the frame N. Near its lower end the screw P2 carries a ratchet wheel Q engaged by a detent g and by a feed pawl Q connected to an operating lever Q2, arranged as clearly indicated in Fig. 7, and carrying on its upper end a roller g u hich is adapted to be struck by the sucker when it descends at the time that it is over the paper magazine, the arrangement being such that the supporting plates lf and L3 with. the pile of paper are raised one step at each operation so that the top sheet of paper will always be in proper position to be engaged by the sucker. lt is very difficult to malte this feed absolutely correct and some means must be provided for correcting imperfections. One of the 'devices which l employ for this purpose is illustrated in Fig. 7. The feed pawl Q is connected hy a bell crank lever Q5 with a bent rod Q4 connected at its outer end to a vertical rod Q5 pivoted at Q5 to the frame N. The rod Q5 is engaged by a lever Q7 pivoted at to the 'nut P and having an arm extending under the bottom plate lf of the paper magazine beneath the bolt Z5. Should the pile of paper be raised too rapidly so that the sucker on its descent produces abnormal pressure, the false hot-tom L u ill yield and will cause the lever Q7 to be so operated as to cause the withdrawal ofthe feed pawl QI' and thus stop the feed temporarily. This stopping of the feed v. ill continue for one or more additional operations of the sucker, but if not, the pressure on the lever QT will be withdrawn and the feed v)awl will again engage the ratchet wheel Q and continue to feed in the usual l have also provided mechanism whereby when the pile of paper is .nearly exhausted, the machine may be stopped. F ig. 7 illustrates some of the deyi'ces for this purpose. A forked rod R is pivoted to the frame N,

' the tines fr of the form straddling the screw P2 in such position that when theY nut P has been raised to its full extent it will cause the rod it to be operated to raise the end of a latch R', the outer end of which engages an arm s connected with a lever S carrying a belt shifter S. The lever S has a handle s and a weight When the latch R is withdrawn from engagement with the arm s,

the weight S2 will cause the lever to be operated to shift the belt from the fast pulley l) to the yleose pulley lil and thus stop the operation ofl the machine. Therefore, as soon as the pile of paper in the magazine is nearly exhausted, the machin'e will be stopped automatically and all operations will cease.

Should the sucker fail to raise a sheet of paper l have prfrvidedlmeans whereby the 'type bed may be loweredl so that when the sucker descends in the printing; operation it will not come in Contact with the type. T he shaft ym', before referred to, which carries the rollers m supporting the rails M', is 4normally held in its elevated position'by the spring pressure devices T connected to` 4an arm j extending from one of the pivot pins 'm3 and the arm is connected to acrod t carrying on its upper end. an arm t hinged at t to the upper portion ofthe rod. The rod t is slotted at t3 and through this sloty eX- tends a guiding stud t". The upper end of the arm t" is formed with a recessed head t5. lt is obvious that if the rod t is depressed, the rollers m will be lowered, Vthe rails M correspondingly lowered and therefore the type bed will be thrown out of operative position. This is done automatically at the proper time in the following wayz-A cross head T2 is mounted to reciprocate in guides T5 and is connected by a rod T1 with an eccentric T5 on the counteL-shaft F. The

cross head T2 reciprocates continuously during the operation of the machine, but normally has no effect upon the rod t. The arm t of the rod is normally held in the position shown in Figs. 1 and 7 by a rod t7 which is pivoted at is to a bracket T8 extending from the main frame A. The rod is longed and carries a A weight T5. The weighted end of the rod is arranged close to the shank of the rack bar F2 and extends above the laterally projecting arm K10 carried hy the upper end of the piston rod K.`

'mally the arm lx1 does not engage the im rod t7, that is to say, when the sucker engages a sheet of paper such resistance to the up-l ward movement of the'piston is produced that the spring K3 is stretched `to a greater extent than otherwise and the piston rod is not raised to so great an extent as to engagea 105 the rod 7. ln such case the arm K10 wilL rise to a point, such as indicated by dottedA lines at a: in Fig. 17, but when the sucker ance to the action of the piston is not so great, therefore the piston rod will rise to a greater extent, the arm K1 rising tothe position shown 'at in Fig. 17, and lifting the rod t7 so that it withdraws from the arm t and allows it to swing over into the path of the cross head T2. This cross head is formed with a projection t1 adapted to engage the recessed head t5 of the arm t. Therefore when thearm t is simng over to the dotted position, shown in Fi 17, and the cross head descends, the roV t will be forced `downwards, thus lowering" the rails M and the type bed. If on the next opera-y tion the sucker engages a sheet of paper, the arm Kw will not rise to the position a2' and therefore the rod t7 will hold the arm t out of the path of the cross head T2 and thematically in this way Withdrawn from op- 'erative position whenever the sucker omits to carry a sheet of paper thereto.

I have also provided means wherebv should the sucker repeatedly tail to elevate a sheet from the magazine, all the mechanism will be stopped by the shift-ing of the driving belt.. This mechanism is most clearlv indicated in Fig. 17. As there shown, theI bracket T8 carries a toothed segment U pivotally connected with the bracket at u and carrying a detent pawl u adapted to engage teeth u, a, a on the edge of the bracket. The arm t carries a sprinrbr pressed pawl 11.5 which engages the toothed segment U when the arm t is swung over to the dotted position shown in Fig. 17 in the range of movement of the cross head T2. 'Vhen the arm t is first thrown over to this position, the pawl ui will engage the bottom tooth a of the segment and when the cross head T2 first descends the segment will be moved one step downwards causing the pawl u. to engage the tooth un. When the cross head next descends, if the arm t is still beneath it, the pawl a5 being then in engagement with the tooth u will cause the segmentto be depressed another step and should the arm t still remain in the path of thc cross head on the next downward movement thereof, the.

segment will be caused to descend' another step. The outer end`ol` the segment, it will be observed, is connected by a rod U2 .to the latch R, before referred t'o. The manner ol' eol'inecting the rod U2 with the latch, as clearly shown, is by causing the bent upper end ul of the rod to enter a slot 1'1" in the downmirdly projecting arm r" ol` the latch. Normally the segment U is held in an elevatedposition by means of a spring U5 and the bent end u1" of the rod U2 occupies a iosition' at the upper end of the slot 1"". Viren the segment has been depressed .one step, the bent end Ium of the rod will be depressed one step in the manner indicated y dotted lines in Fig. 1`7. When the segment is depressed another step, the rod will also be depressed correspomlinely, but on the third depression of the segment, the

llatch R willbe operated to ithdraw from the'belt shifting lever which will thereupon operate, that is to say, the mechanism is so arranged that should the sucker hul lor three consecutive times to raise a sheet of aper, the machine will be stopped by shiftmibT the driving belt. l have so arrangcdthe mechanism, however, that should the sucker fail for less than three consecutive times to raise a sheet, the parts will be returned to their normal position. it will be observed that the crosshead carries a bent rod V nhich has a hooked lower end Iv that is adaph il to engage. a pine/projecting laterally from the detaiuinpr pawl u. When the arnr f/ is lhsy swung over into the patlrol' the ross head T, the end t of its head t will en# -gage the rod V and raise it to the position shown by dotted lines in Fig. 17, so that, as the cross headrises, the hook o will not encounter orengage with the pin v, but as soon as the arm t passes back to its normal position, indicated by full lines in Fig. 17, the rod V will drop and therefore on the next upward movement of the cross head T2 the hook o will engage the pin o and thus raise the detaining` pawl, permitting the parts to assume their normal position. The rod t is provided with a bell hammer t1" cooperating with a gong t. vThis is for the purpose of notifying the attendant when the machine is not operating in its normal way. Three strokes of the bell will indicate that the machine has been sto ped. The rod TIwhich operates the cross ead T2 also operates the inking roller W which is carried by arms W pivot'ed at w to the main frame and connected by a link w with an arm w2 connected to a shaft w3 carrying an arm w"1 bifurcated at its outer end andenvaged by a pin wf on the rod T. The ink disk 106 is connected with a )late 107 which is pivoted to the bracket 108. "he disk 106 has an annular series of teeth 105 on it with which engaves a pawl 104 pivotally connected with a bell crank lever 101. The pawl is connected to move with an arm 102 in turn connected by a spring 103 with the bell crank level' 101. This lever is connected by a rod 100 with the lever 'wt In this way the inkin(r disk is rotated to. properly supply ink to the roller W.

The deliverer for the printed sheet is preferably of the form shown in perspective in Fig. 18, comprising sides supporting Wire netting x3 and having downwardly projecting arms x" pivotally connected at f" to the frame N. Springs c secured to the frame N and to the arms 1'* tend to withdraw the dc- `liverer from position above the type bed O.

One of the arms .t4 is connected by a link x7 with a plate 11; which is slotted, as shown. andthrough this slot extends a )in s attached to the frame N. The plate x is formed with a tooth ad" at one end and with a recess .r1.1 at the opposite end. A'spring hook X2 is secured to the cross head l of the sucker and adapted to engage the tooth '.v" of the plate x8 when the sucker moves downward and the type bed is below it. When in this latter condition the plate te is disposed, as indicated in'Fig. 5, andas at this time the sucker is above the type bed, the hook will on the upward movement of the sucker engage the plate w3, shift it to the position shown in Fig. 4 against the tension of the spring w and move the dcliverer to the `position shown in Fig. 4 where it will receive the printed sheet when dropped by the sucker. lt will be understood that-as soon as the sheet has been printed and raised from the type bed, the suction is withdrawn and the Operation is reversed, the sheet being vagainst the upper portion thercot` forced by pneumatic pressure away from the sucker. The deliverer is held in its elevated position by the pressure ot the hook X2 upon the plate x8. As soon, however, as the type .bed is shifted, the pressure of the hook X2 is Withdrawn and the springs w will cause the deliverer to be moved to the position shown in Fig. 5 and deposit the printed sheet in a suitable receptacle. Should the springs fr fail for any reason to o ,erate, l have provided for the positive actuation of the deliverer by connecting to the arms c downwardly projecting rod x15 arranged in the path oi a pin X16 attached to the support M, the arrangement being` such that at the proper time the pine1G will engage the rod :1:15 to cause it to actuate the deliverer in the manner above explained. v

In order that the machine may properly operate upon folded sheets of paper, l have rovided the devices particularly illustrated in Figs. l0 and l1. It is obvious that the sucker would not properly hold a folded sheet by mere suction as the under part ot the folded sheet would drop by gravity to the position indicated, for instance, in Fig. l1. have therefore provided -devices tor holding the bottom portion of the. `folded sheet up and l automatically operate these holding devices to engage the folded sheet immediately after it is raised from the magazine and to disengage .therefrom after the sheet has been printed. The holding device comprises a rod Z having arms .2 connected at their outer ends by a rubber band z, or other suitable connection. The rod is pivotally mounted in suitable bearings e" and .has a cranked portion z3 connected by a vertical rod z" with the arm z5 ot' a toothed segment Le attached to the cross head l" ot the sucker. 'llve segment a engages a row oi" teeth e7 of the horizontally arranged bar Z adapted to slide in guides e and carrying rollers e", el" between which is arranger'i a cam Z2 havingl three projections e and three corresponding depressions 222. Vvhen the roller e" is in a depression of the cam, the roller 2' engages a projection thereof'. 'The cam is connected to rotate with a ratchet Wheel Z3 which is engaged by a detent pawl Z4 and is adapted to engage a dog Z", the shank otl which extends through a suitablr` .trame Z and it is normally pressed ,towards the ratchet Wheel Z2 by a spring Z7. The shank ol" the dog Zr" is provided with a handle Zs by' which it may be moved into and out of operative iosition, it being understood that when singl, sheets are operated upon, the dog is held out of operative position, but when folded sheets are being used, the dog is allowed to move into the path oi the ratchet wheel Z2. When the sucker descends into the magazine, the

holder Z is in the position shown in Fig. 11,

but as the sucker rises out of the magazine, the ratchet wheel Z3 is engaged by the. dog Z5 and is turned the distance of one tooth, causing the bar Z to be moved to the left as viewed in Fig. 10, thus causing the holder Z to move over to' a position below the'sucker and hold the folded sheet against it. The holder will remain in this position untii the sucker has again descended, caused the sheet .tp be printed, and'again moved upwards, on which upward movement the ratchet Wheel yill be again moved but in such manner as to cause the bar Z to be shifted to the right and thus cause the holder Z to be Withdrawn. it will be understood that the mechanism is such vthat the sheet of paper, envelop, card, or the like, is held in positiontor printing by suction, but that as soon as the sheet has been printed, the suction is withdrawn and the operation is reversed, the sheet being forced by prieur-natie pressure away from the sucker. I

in Figs. l?) and 20, l have shown a modification in which the vmagazine L and the type bed 0 are held in aviixed position, while the cross head l carrying the sucker J, in addition to being reci procated, is oscillated. in this modification the cross head l. is mounted to reciprocate in suit-able guides IW which swing about a shaft l. The cross head is vconnewed by suitable lever mechanism, in the manner indicated, and by an eccentric i12 with an operating shaft Il? which may be located and operated in the vsamev manner as the counter-shaft i?, before referred to. The Asupport L" tor the magazine and the type bvd is adjustable by means of an adjusting screw L so that the magazine and the type bed may be heldin proper relation with the' sucker as it reeiprocates and oscillates. In other respects the construction and operation of the mechanism is the same as that bel'ore described and similar parts are correspondingly lettered.

ln i"igs. 21 and 22, l have shown an organization in which the sucka is made to reciprocate in stationary guides While the type bed, when in printing position, is arranged above the top of the paper magazine.. In the mechanism shown, the sucker is arranged to reciprocate in guides O2 and the paper magazine L is provided with arms or wings L" adapted to nieve vertically in guide recesses L21 in the giiides O3. The arms or wings L20 are connec ed in the manner shown to ecccntrics L22 on a shaft L23 carrying a toothed segment L24 engaged by a recipiw'ating rack bar L25 operated, in the manner indicated, from an eccentric L26. By this mechanism the iaper box is made to .move upv and down. -Vihe frame N of the type bed is pivotally connected, as indicated at X20 to the guide frames Oa and it is formed withcurved slots Z21 through which extend drawing device and platen to press a sheet lthe mechanism' being so timed that the sucker will descend and raise a sheet of pa# er from the magazine while the type bed is in the position indicated by dotted lines in Fig. 22, and will then descend with the sheet of paper upon the type when the type bed is in the position indicated by l'ull lines in Fi 22.

n Fig. 23 I have illustrated a further modification in which the sucker is arranged to reciprocate vertically in fixed guides and the magazine and type bed are made to oscillate about a horizontal axis. As shown, the magazine and frame N of the type bed are pivotally connected with va rod N1" and the t'rame N is connected by a rod Si with a bell crank lever S in turn connected 'by a rod S7 with an eccentric S8 which operates to move the magazine and type bed bachtand forth from the position shown by full lines to that. shown by dotted linesvand vice versa. This` ligure of the drawing also shows the deliverer for the printed sheet, butas'the operation is similar` to that hereinbefore described, 'no

Hfurther description ot` this mechanism is nec essary in this connection.

I have described what I call a pneumatic withdrawing device or sucker. lt will be iinderstood that tluid pressure of other lkinds may be emy'iloyed. The mechanism shown is arranged to stopthe operation ol the inachinc should the sucker fail lor three consecutive tiincs to raise a sheet of paper troni the magazine, but ot course it ma)rv be arranged to thus operate when the sucker has failed twice or a greater number of times to perform this operation. it will bc understood that the machine` is adapted to operate on single sheets ot' paper, folded sheets, cards, envelops, etc.
